I had a very hard time getting through the grid even once. dopterr was having trouble finding stars (skipping 33 out of 45). At one point, I aborted the grid and tried to refocus, since the focus had changed dramatically. Then started a new grid. Still failed at low altitudes. I think this was due to two main complications: 1. at low altitudes smoke was definitely a factor. Most of the stars at alt's 1u per 0.1 cubic feet. TELESCOPE STATUS Telescope drives operational.
